GA'S HEATING APPARATUS.

SPECIFIGATION formng part of Letters'Patent No. 253,850, dated February 21, 1:882.

Application filea July 12, 1881. (Modem To all whom t't may concewz:

Be it known that I, SAMUEL DARLING, of Providence, Rhode Island, have invented a new and useful Improvement in a Gas H eatin g Apparatus for Domestic and other Purposes; and I hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a full, clear, and exact description of the inventon, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to make a gas heating apparatus th at will produce more coinplete combustion of gas and be more convenient and economical than anyheretofore in use, and which can be run with the least as well as With the largest amount of gas required for domestic purposes; and it consists in making a gas-burnerin which the gas and air are united in the right proportiou to produce the most effective combustion when the largest as well as the least quantity of gas is being used; a burner without perforated plate at the burning-aperture, having a single narrow and continuous combustion-aperture, and iu which the gas will not take fire in the gas-chamber with the least pressure of gas a burner in which the gas and air will be heated to a high degree before combustion 5 a double gas-burner having two gas and air chambers and two gascocks so arranged that both may be run logether or either one without the other; a double burner with one part larger than the other; a ring gas-burner, the gas being burned on the inside and outside of the rin g a burner having a gas-deflector in the mixing-chamber against which the gas impinges as it enters; a gasburner having a regulator to regulate the quantity of air to be mixed with the gas, theregulator being moved automatically as the gascock is turned and also a gas-burner having a radiator which is a slow conductor of heat, to

receive the heat thrown outward from the gas and radiate it back upon the kettle or article being heated. i

The use of gas for cooking and other purposes is rapidly increasing. Though more eX- pensive than oil it is much more convenient,

eleanly, and safe, and the more wealthy class of people will use it instead ofoil. Oil-stoves require a great deal of attention and labor to keep them in order, and doubtless the time it takes to keep the oil-stove4 in goodworking Condition is worth more than the diiferencein the cost of gas and oil.

One great defect in the gas-burners now in use is that a burner burning suffieient gas for domestic purposes generally cannot be run with as little gas as is required to be most con'- other, and so arranged that both parts can be run together or either part without the other, the smaller part requiring an extremeltv small quantity of gas to run it. i

With the burners nowin use the flame is not evenly spread over the surface of the article being heated. Withmy burner the heat can be applied evenly all over the bottom of the kettle or article being heated, or applied according to the work'being done.

In most gas-burners in use the tia-me is not sufficiently steady, and especially when little gas is being used. In my improved burner the flame is perfectly steady when the least gas is being used, and it produces more complete combustion of gas than any within my knowledge with less offensive odors.

Another defect in the gas-buruers heretofore in use is that the air is not mixed With the gas in the right proportion 5 but in my burner there is a regulator which can be adjusted to regulate the ingress of the air to agree with the quantity of gas used, and there is also a great loss of heat in the burners heretofore in use from outward radiation from the flame, which I prevent in my burner by having a radiator which is a slow eonductor of heat, to receive the heat radiated outwardly from the flame, and throw it back upou the article being heated, the radiator soon becoming very hot and adding much to the heat of the gas.

In the accompanying drawings I have illustrated a gas-heating apparatus embracing my improvement, in which- -Figure 1 represents a top view of a singlering burner Fig. 2, a vertical central section of a single-ring burner and part of the gas and IOO air chamber; Fg. 3, a vertical central section of a single-ring burner having a radiator and kettle; Fig. 4, a vertical central section of a single-rin g burner having a radiator, flat-iron, and flat-iron protector; Fig. 5, an air-regulator; Fig. 7, a horizontal section of a doublering burner through line w m, Fig. 8; Fig. 8, a vertical central section of a double-ring burner.

The letter A represents a hollow-ring gasburner made in two parts and fastened together with screws D; B, the central part of the ring and the smaller part of the burner; O, inlet gas and air pipe and mixing-chamber; D, screws that hold the two parts of the burner together; E, combustion -aperture; F, lower part of a slow-conductor radiator; G, upper part of the same; H, a kettle; I, frame that supports the radator and kettle or other artiele being heated. The radiator is made in two parts, the lower part being fixed and the upper part removable and changeable in size and shape to fit different articles to be heated. J is a fiat-iron; K, an iron to keep the blaze from the flat-iron; L, a radiator adapted to heating flat-irons; m, arms attached to frame I, which,

in connection with the projections a, support the kettle or article beiugheated; O,theinterior of the larger part of the burner; P, the interior of the smaller part of the burner; Q, sl'otted rin g outside of the gas and/air pipe and mixing-chamber R, which is also slotted to correspondwith the slots in the rin g Q S, gasdeflector to spread and mix the gas with the air as it enters; T, gas-coek; U, perforated plate placed at a distance from the burning-point in that form of burner to more thoroughly mix the gas and air; V, projection on thehandle of the gas-cock that turns the slotted ring Q; W, the gas and air pipe and mixing-chamber to the smaller part of the burner P; Z, the gas and air pipe to the outer and larger part of the burner O.

My improved burner may be made of iron or any suitable material. The slow radiator is made of clay, preferably, and fired like firebrick. The Opening (aperture) at theburningpointis about one-fortieth of an inch. The partition Y between the two parts of the double burner may be made gas-tight by facing off the two surfaces, so that they will make a good joint when screwed together, or by any other known means of doing such work.

Having described myinvention,whatI elaim, and desire to secure by Letters Patent, is-

1. A gas-burner having two narrow continuous combustion-a'iertures, one larger than the other, the larger one being in the outer and the smaller one in the inner Contour of the burner, substantially as described.

2. A double gas-burner in one piece, having in combination two combustion-apertures, one larger than the other, the larger one in the outer and the smaller one in its inner contour, a partition within the burner dviding it into two gas-chambers, and a supply-pipe and gascoek for each chamber, substantially as described.
